To all whom zit may concern:

Be it known that l, WILLIAM J. HOUGH, a citizen of the United States, and a resident of the city of Albany, in the county of Albany and State of New York, have invented. new and useful Improvements in Traps for Waste- Pipes of Sinks, cbc., of which the following is a specification.

My invention relates to traps for use with waste-pipes of sinks, washbowls, bath-tubs, and other vessels from which waste water is discharged; and itconsists of the novel devices and combinations of parts and devices, as hereinafter described, and set forth in the claims.

The objects and advantages of the invention will be fully understood from the follow-` ing description and the claims when taken in connectionwith the annexed drawings, forming a part of this specification, in which- Figure l is a plan embodying my invention, showing parts broken awayfor expos-- ing hidden parts in the same. Fig. 2 is a section illustrating the same applied to a sink. Fig. 3 is a section of the same, taken in the transverse at the line of the vertical axis of the waste-pipe in Fig. 2. Fig. 4 is a section illustrating my invention applied to a washbowl-l Similar letters of reference refer to similar parts throughout the several views.

In the drawings, A is a well having its walls of metal and water-tight, and is provided with a removable strainer B, which may be flat or concavo-convex or of any othersuitable form.

O is a bush which is circular in form and integral with bottom CL of said well and has its lower end portion provided with the inclined seating-surface c, and its bore c is made tapering from its upper to its lower end to adapt it to serve as a taper-form seat for the hollow or perforated stem of the body of the trap supported in the said well.

D is the waste-pipe, the upper end of which is flared outwardly in its walls all around at an angle of incline corresponding with the incline of the seating-surface c of bush C, which this iiaring portion receives, and also is provided with rim d, which is integral with the flaring portion of said waste-pipe.

E is a coupling collar or piece having a central perforation e of size and form adapted to receive the Haring portion d of the upper end of the waste-pipe below its rim d.

F F are suitable coupling-bolts which bolt with the bottom of the well A and the lateral flanges e of said collarE, as practiced by the trade for securing a waste-pipe to a dischargenipple of a water vessel. -A

G is the body of the trap, which body is sectional and comprises the lower-half piece G and the upper-half piece G2, which latter is removable at pleasure from the former. These pieces G G2 are secured together by any suitable means,- soas to be Water-tight in their joints. The lower-half piece G comprises two ormore cup-form walls h, having intake-openings I in their lower sides and integ-ral with the centrally-perforated swiveling stem h'. These cup-form wallsh are projected horizontally outward from the upper end of said stem ZL', while the lower-half portion of said, stem is on an inclination of outside'surface which is in correspondence with the inclination of the inner surface of the wall of the bore c of the bush in which the stem h is to be seated. The upper-half piece G2 of this trap-body comprises in a singlepiece horizontal portion g, integral with the inverted-cup-form walls 71,3, which latter are in number, diameter, and relative position corresponding with the cup-form-Walls h in the coacting half-piece G with which this upper piece G2 is secured. In small sizes of these traps these two pieces G' G2 may be secured together by. means of binding-screw G3, passed through the upper side wall g of piece G2 and screwing into the bar g', connected to the lower piece G', and a packing-washer g2 between the head of said screw and wall g produces a water-tight joint between the latter and said screw. A suitable packingsubstance g3 between the pieces G G2 at their outer edges makes the joint of said pieces water-tight. When these sections or pieces G G2 of the trap are secured together as shown, the wall portions h 7a2 of these pieces produce the lobes G4, which inclose by each pair of said walls a valve-chamber H, having communication with the vertical dischargeopening H2 through the horizontal passageways l-I, contained between the horizontal IOO wall portion g of piece G2 and the upper end portion of the lstem 7L' of piece G'. Within each valve-chamber I-I of the series in the trap is a suitable valve J, which operates independently of those in the other valve-chambers. These valves J work upwardly within the said chambers, and I at present prefer them to be of the kind known as ball-valves,

having their diameters larger than those of the intake-openings I. 4They are intended to open for entrance of water into the trap and to close against backflow of either water or gas, and they are of any suitable substance not liable to be affected or changed by action of water.

This trap is shown to be in the lower portion of the well A and supported by its stem h' from the inclined internal seat c, formed in the depending bush C, and may be held from raising out of place by any suitable means, yet I prefer to secure traps of small size for ordinary house use with interlocking devices, as catching devices 7a, connected with the upper end portion of bush C and the coacting inclined holding-lips 7e', made integral with the outer side of stem 7L' of the trap.

In Figs. 1, 2, and 3 this invention is shown to be applied to an ordinary kitchen-sink and the said well A is shown to be sunk below the plane of the bottom s of the sink, while the strainer B is shown to be fiat and on a plane with the said bottom s.

In Fig. 4 the invention is shown in section to be applied to a washbowl W by being connected with the usual discharge-bushl w by means of a pipe L of suitable size and length and coupled in a water-tight manner to said discharge-bush and the close coverA of the well A, which latter is shown to beprovided with a removable strainer B, having a concave form of upper side and seated by its rim Z1 on a suitable support '11', integral with the' side walls of said well. The trap and the adjuncts thereof and mode of coupling the wastepipe I are all made, preferably, as shown in Figs. l, 2, and 3.

Although the trap-body G is shown to comprise two lobes h h, yet in some cases traps comprising three or more lobes h (havin g their chambers II and their inlet-openings I, having valves J and communicating with the discharge-opening H2) may be employed to secure large capacity without departing from the spirit of this invention. This Well and its inclosed trap and their adjuncts may be applied to washbowls, sinks, bath-tubs, washtubs, cesspools, or other water-receptacles with great ad vantage in that the said strainer prevents coarse foreign substances passing into the well, while settlings of vsubstances of greater specific gravity than the water into the lower portion of the well, below the trap, is provided for, so that such substances may not be carried into the inlet-openings to the chambers of the lobes to foul the same; further, access may readily be had to the chamber of the well for removal of any accumulations therein of-foreign substances.

Having described my invention, what I claim, and desire to secure by Letters Patent, is

l. In a trap for sinks, waste-pipes, tbc., a sectional trap formed bythe combination with alower section or piece G', comprising a downwardly-projected central stein having through it the discharge-opening from the trap and tapering outer side to adapt said stem to seat in a tapering seat so as to be readily removed therefrom, two or more similar cup-form walls h integral with said tapering perforated stem and extended horizontally from the upper end portion of the latter and provided, each in its lower side with an intake-opening I, of an upper section or piece G2 comprising a series of in verted-cup-form walls h3, in number, dimensions and relative arrangement corresponding with those in lower section G, and made integral with a horizontal middle portion g, p

means described securing said sections together in a water-tight manner, and producing between said walls h 7L valve-chambers H, and horizontal passage-ways communicating from said chambers to the discharge-opening in said central` stein and valves within said chambers adapted to open and close the intake-openings thereto, substantially as and for the purposes set forth.
